V Sloveniji se razvija sistem usklajenih podatkov in drugih informacij o vodah in na vodo vezanih elementov. Sistem bo podporno orodje za načrtovanje upravljanja z vodami. Sestavljajo ga preverjeni podatki in agregirane, logično integrirane informacije o stanju voda v Sloveniji, pritiskih in vplivih na vodno okolje in varstva voda. Podatkovni viri so nacionalne podatkovne evidence in sistemi spremljanja stanja. Koncept smo razvili na prototipu. Sestavljen je iz neodvisnih informacijskih tematskih slojev, ki so organizirani po principih geografskih informacijskih sistemov in pripravljeni za brskanje po notranji in zunanji elektronski mreži.In Slovenia, the system of harmonized data and other information on water and water related areas is being developed as a support tool for water management planning. The system includes verified data and aggregated and logically integrated information on the state of waters in Slovenia, the pressures and impacts on water environments, and their protection. National information evidence and monitoring systems provide the data sources. The concept has been developed by way of a prototype. The system consists of independent data, organized by information themes with the logic of geographic information systems and prepared for browsing with intranet and internet
